Quantum entanglement is a physical phenomenon that occurs when pairs or groups of particles are generated or interact in ways such that the quantum state of each particle cannot be described independently of the others, even when the particles are separated by a large distance—instead, a quantum state must be described for the system as a whole.
To me, the important part of this extract from Quantum Entanglement: Wikipedia is the phrase pairs or groups.
I might well be getting bogged down in circular reasoning, or plain old semantics, but my question is:
Is quantum entanglement, based on this definition above, or a better one if you know it, a property inherent to a particle, (that is not revealed until it decays and needs to comply with various quantum numbers) or, because entanglement only occurs after the decay, can it be considered a process?
My point here is analogous to the change in energy level of a electron when it absorbs a quantum of radiation, it produces an unstoppable, indivisible event. My source for this assertion is Bohm's 60 year old basic primer, (Quantum Mechanics, so I could be basing my question on out of date information).
To me, this chain of events is not an inherent property of an electron, (it is not, directly at least, listed in the Standard Model). It is a process of emitting radiation.
If I am confused by my ignorance, or indulging in hair splitting, then my apologies. If the answer is, how do we categorize an as yet not understood phenomenon, then that's something I will obviously just have to accept.
This related question Entanglement, a subjective or objective property, says it is an objective property, but I am not asking precisely the same question,at least, I don't believe I am.
There are plenty more related questions on this topic, and I will delete this post if it is not asked properly, not thought through sufficiently or already answered.
